Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

2015 Mazda2 spotted in Japanese magazine

The styling changes at Mazda are proceeding at a fairly quick tempo. The CX-5 was unveiled, followed by a refreshed CX-9, the excellent Mazda6, and most recently a new Mazda3. This all happened over the course of less than two years, which in the auto industry is like a long week.
Now the Mazda2 is getting its revamp. Thanks to a magazine scan from Japan, we now have our first look at the new sub-compact, called the Demio, in its home market. Mazda's familial front end has been fitted, and it doesn't look quite as suited to the smaller car. Lacking the long-hood look of the Mazda3 and Mazda6, the new styling looks overly rounded, almost bulbous from our angle. It's still attractive, but the shape is kind of off-putting compared to the chiseled faces of the 2's big brothers. We'll concede that the folded magazine page may have something to do with it, however.
The next-generation 2 should adhere to Mazda's Skyactiv philosophy, which means we can expect a highly efficient four-cylinder engine, although it's impossible to say if Mazda will do away with its smallest offering's one-engine strategy. Considering the Mazda2 will be riding on a shortened version of the CX-5's platform, we'd expect some degree of mechanical parts sharing, regardless of how much the larger platform needs trimmed. Perhaps a detuned version of the 2.0-liter, Skyactiv four-cylinder could be under the 2's hood?

Mazda recalling 18k Mazda6 and RX-8 models over airbag inflators

Faulty Takata airbag inflators keep taking their toll on automakers. Mazda is the latest to be affected in the US by announcing a recall covering 18,050 Mazda6 and RX-8 models to replace the front, passenger-side airbags. Specifically, the campaign covers 18,000 Mazda6 units from the 2003 and 2004 model years built between May 29, 2002, and March 4, 2004, and 50 RX-8 vehicles from the 2004 model year made between June 25, 2003, and June 30, 2003.
As with the rest of the vehicles with these faulty inflators, it's possible for the part to rupture when deploying the airbag and potentially spray shrapnel at the occupant. Mazda's defect notice goes into a bit more detail than most about the problem saying: "some propellant wafers have been produced with an inadequate compaction force, or may have been exposed to uncontrolled moisture conditions (those wafers could have absorbed moisture beyond the allowable limits)."
This isn't Mazda's first difficulty with Takata-supplied airbags this year. The company was among the seven automakers that recalled vehicles in hot-weather states over the inflators. It also had to recently fix 42,000 Mazda6 vehicles in China over the issue.
